2 Claims.

This invention relates to load-bearing pile con structions and particularly to the formationtof a tapered enlargement thereon.

An object of the present invention is the provision of enlargements t'othe normal bearing pile section only inthat portion of the pile which is in firm load-carrying soil. l

A further objeotofthe present invention is to provide laggingmembers upon the face of the flanges with the lagging members tapering so that the pile will develop high load capacities in clay or cohering soil.

Other objects and advantages will become apparent as the description proceeds, and reference is had to the accompanyingdrawing in which:

Figure 1 is an-elevation showing the pile provided with tapered timber lagging members fastened to the faces of the flanges of a conventional type H or I-shaped beam;

Figure 2 isan elevation taken at right angles to Figure Land showing the cap members for theztop and bottom of the lagging members; Figure 3 is asectionon the line III-III of Figurel; I

Figure 4 is Figure 1; and, H 1

Figure 5 isja section on the line VV ofiFigurel. i i

In the drawing, the numeral" Zrepresents the asection a the line IV-IV of main body portion of the bearing pile and comprises a conventional type H orI-shaped member extending down through the water and mud into thestratum of firm soil. On that portion of the main body 2; which vided a. tapered enlargement 3. This enlargement,as shown in the figures, comprises wooden lagging members 4 secured to the flanges 5 of i the H or I-shapedqmember by bolts or other securing devices 6. shown as being formed of timber, may be, if desired,. suitably formed metallic sections, precast concrete sections, or other. suitable material, and, ineach instance, the lagging members aretaperedandgradually become smaller downflanges and an oppositely disposed downwardly ward from the top of the enlarged portion.

These lagging members are provided'with a straight face which abuts the outer faces of the Secured to the top of the lagging members, by

belts or other securing devicesl, are metallic angle members 8. These metallieangle mem 55 bers are provided with notched portions 9 to The lagging members, while receive the flanges 5 of the H or I-beam to which they are rigidly secured in any conventional mannensuch as by Welding or the like.

At the lower end of the tapered enlargement, metallic angle members 20 are welded to the flanges of the H or I-beam in order to provide a support for the reduced end portion of the lagging members and protect said ends during the drivirlgoperation as well as to form a rugged "offset capable of forcing its way through the soil under driving operations.

Under the present construction, there is provided a bearing pile construction having a tapered enlargement which increases in width or size towardits upper. end and which is of materially greater cross-sectional area at the upper end than at thelower end when applied to the H or I-beam. This produces a bearing pile havshort length of point section. so that the mate rial in the pile above the point section can be utilized to better advantage.

1 In a steel bearing pile having an H or I.--

shaped cross section, lagging members secured to the outer faces of each flange of said bearing-pile over. that portion of the pile which is in firm load carrying soil, the outer faces of said lagging members tapering gradually downwardly from the upperedgetoward the bottom edge to form in combination withthe pile an area on said pile having a tapered enlargement and means for securing said lagging members tosaid bearing pile.

2.,In asteel bearing pile having an H or I- shaped cross. section, lagging members secured to the outer faces of each flange of said bearing pile said lagging members each having a straight surface abutting the straight faces of said tapered surface forming in combinationwith the bearing pile a tapered" enlargement over that portion of the bearing pile which is in firm load carrying soil, plates secured tolsaid bearing pile for protecting the ends of said lagging'members and means for securing said lagging members to said bearing pile.
